In-memory token ledger pattern for tracking intermediate balances during multi-step operations within a single transaction. Use when building any contract that processes sequential token operations — aggregators, batch processors, atomic swaps, or multi-step DeFi flows.

When a contract executes multiple token operations in a single transaction (e.g., swap A→B, then B→C), you need to track intermediate balances without writing to storage. Storage writes are expensive and unnecessary for temporary state that only lives within one call.
| Multi-step token operations in one tx | Yes | | Need to track balances across sequential operations | Yes | | Single deposit/withdraw | No — overkill | | State that must persist across transactions | No — use storage |
